Subject: Given a grid of squares and the 4 corner cells coordinates, find all the others

Hi there,

I have a photo of a grid of squares, 8 lines and 16 columns. I have also the x,y coordinates of the cells in each corner. How can I find the coordinates of the center of all the other cells? The grid may not be aligned with the x and y axis of the image.
